For continuous filmsthe resonance frequency is ferromagnetic resonance frequency(FMR)caused by its own material characteristic. The resonance ferromagnetic frequency is determined by saturation magnetization (Ms), anisotropic field (He), and damping factor (α). All this timeresearchers try various methods to control these variates above-mentioned to achieve FMR required. As is well-known, the pattern...
Soft-magnetic amorphous alloys based on the ferromagnetic elements Fe, Co, Ni and their combination have attracted increasing interests since the discovery of the Fe-P-C system in 1967, because of their excellent soft-magnetic performances including high saturation flux density (Bs), low coercivity (Hc), high permeability, low core loss, and so on. By devoting subsequent great efforts, a variety of...
With the rapid development of high frequency and microwave technology, soft magnetic thin film with high saturation magnetization and high permeability, has been intensively studied in the several decades. In recent years, many research effort have been placed on the controlling of resonance frequency (fr)[1-3]. One of the useful ways to tuning the fr is by patterning the magnetic thin film into periodic...
In recent decades, magnetodielectric (MD) materials have attracted a great deal of interest for both their unique physical properties as well as their potential as enabling materials in such applications as memory devices, electric field-controlled microwave resonance devices, etc.[1]. The magneto-electric effect has been observed in nature for very few single-phase materials, but many multiphase...
Due to their large conversion between magnetic and electrical energy at room temperature, multiphase magnetoelectric or multiferroic materials have received considerable attention from the Spintronics' community.[1] The multiferroic composites or heterostructures are considered to have great potential use for next generation multifunctional devices such as sensors, transducers, filters, high frequency...
Magnetoelectric (ME) couplings in multiferroic composites exhibiting simultaneous ferromagnetic and ferroelectric phases through strain-mediated interactions have attracted great interests for their promising technological applications on magnetic sensors, energy-harvesting devices, four-state memories and microwave resonators[1, 2]. Initially, the research on magnetoelectric materials focuses on...
FeSiCr ternary alloy, as an electromagnetic wave absorbing material, have received much scientific and technological attention in Military and Civilian application domains. For the fundamental scientific research, compositional studies have been conducted for FeSiCr ternary alloy, e.g. Fe80-xSi-20Crx (0≤×≤20), Fe75Si15Cr10, Fe80Si10Cr10, Fe80Si20Cr10, prepared by melt spinning [1]. But studies about...
This paper reports on magnetic properties of bulk polycrystalline samples of ln2O3 doped with a wide range of TM ions. Phase purity of the samples was analyzed by means of X-ray diffraction and conductivity was also measured using a four-probe technique. From magnetization-temperature curves (M-T curves), it was shown that Cr doped samples was found to be paramagnetic throughout the whole temperature...
This paper presents a complete scheme for simulation of single-phase transformers with internal faults. Traditional methods may not be effective in displaying hysteretic characteristics in the transformer core. The approach in this paper uses transmission line method (TLM) incorporating Jiles-Atherton model to introduce nonlinear hysteresis. A small 25 kVA 11 kV/220 V power transformer with turn-to-earth...
